I have been searching for a way to add some cover songs without having to upload them to this hosting site . Because of the limits of this specific "package" it was not feasible to to just some coding and uploading, so I ended up using soundcloud.com as a site which will host the music and also because of the mp3 player they offer. I will see how it goes in terms of visitor to move on to add more cover samples or just leave the three already present.
